These days I usually travel in larger blocks of time, like month to 6 weeks. I can almost always be assured of catching a cold somewhere along the trip. You'd think that by this time I would have enough foreign bugs roaming around in my system that they could fight off new foreign bugs but it is not to be so. My husband has been fighting a cough which he has jokingly called his Piglet flu. Now I think I have it as well. Drat. I do have enough cold tablets and such that I can fight it but it does mean some slow moving for a couple of days. On the trip to Central America in June, spent one afternoon sleeping fighting off piglet flu there. Hopefully I can keep upright for this trip and stay somewhat healthy. Not off to a good start this week.
